Circuit breakers are electrical devices designed to protect circuits and equipment from damage when too much current flows through them. The 219-3-40140-02 is a type of circuit breaker specifically designed to protect low voltage circuits. It is suitable for use in commercial, industrial and residential applications.

The 219-3-40140-02 has two discrete functions: overload protection and short circuit protection. The overload protection feature prevents equipment or devices from being damaged by regulating the flow of electricity when the current exceeds the rated maximum current, while the short circuit protection function limits the current in the event of a short circuit, preventing excessive heat and fire. These functions work in tandem to protect circuits from damages caused by high currents.

The working principle of the 219-3-40140-02 circuit breaker is relatively simple. It consists of a bimetallic strip, an overload device, the electromechanical trip device, and the short circuit trip device. When the current through the circuit exceeds the rated current limit, the heat generated by the current will expand the bimetallic strip, which will then actuate the overload device, resulting in an abrupt interruption of the current. This interruption can also be triggered manually, by pressing the button of the electromechanical trip device. For short circuits, the same process applies, but the current interruption is caused by the short circuit trip device, which senses the current level and releases the interruption mechanism.

Within the field of electrical protection, the 219-3-40140-02 circuit breaker is an ideal choice due to its versatility and dependability. It is suitable for both residential and commercial use, and is able to accurately monitor and respond to current in both overload and short circuit situations. As a result, the 219-3-40140-02 is becoming an increasingly popular choice among electrical engineers and homeowners alike.
